What’s New in CoventorWare® 10

The CoventorWare 10 suite features a new, fast-frequency-sweep algorithm for analyzing piezoelectric bulk acoustic wave (BAW) resonators such as FBARs and higher-mode resonators such as laterally vibrating resonators (LVRs) and contour-mode resonators (CMRs). Currently, most simulations of these types of resonators are done in 2D because full 3D simulations can take days to complete. Using the unique fast-frequency-sweep algorithm in CoventorWare, 3D simulation results for the full frequency range of interest typically can be obtained in under an hour (at least 10X faster than the competition). This greatly reduced simulation time makes it feasible to perform design studies to mitigate the effects of spurious modes that are not predicted by 2D analysis. The routine setup and post-processing tasks required to simulate a multi-port device and extract Butterworth-Van Dyke parameters have been completely automated with a script. The script even outputs Touchstone-format files for use in RF circuit simulators such as Keysight Technologies ADS.
